slightly yellow to beige-green crystalline powder | [Uses]
It is employed in the spectrophotometric analysis determination of methenamine and its salts. It is also used in the detection and repair mechanism of Etheno-DNA adducts. | [Synthesis]
General procedure for the synthesis of 2-hydrazinobenzothiazole from 2-aminobenzothiazole: Hydrazine hydrate (1 equiv.) was dissolved in ethylene glycol at 5 °C. Under stirring, concentrated hydrochloric acid (2 mL) was added slowly and dropwise, followed by 2-aminobenzothiazole (1 eq.). The reaction mixture was heated to reflux for 2-3 hours, after which it was cooled to room temperature. Upon completion of the reaction, the solid product formed was collected by filtration, washed with water and purified by recrystallization from ethanol to afford the target compound 2-hydrazinobenzo[d]thiazole (32). The product was white crystals in 90% yield with a melting point ranging from 200 °C to 202 °C. 1H NMR (DMSO-d6, 400 MHz) data were as follows: δ 4.84 (2H, s), 6.85-7.65 (4H, m), 8.62 (1H, s). ESI-MS (m/z) analysis showed the molecular ion peak as 166 (MH+). | [References]
